Sound is missing from all clips

If sound is missing from all clips in all projects, then do the following tasks in order:

1. Choose a system default audio device and check its volume.

Your computer could have more than one device that can play back audio (e.g., an internal speaker, external speakers, or headphones). Set your preferred device as the system default sound playback device, and then verify that its volume is not muted or set low.

Windows

Use the Control Panel to check your default audio device and its volume setting. If you need additional help using the Control Panel to check these settings, use the following Microsoft Help links:

If you don't hear sound after completing the tasks above, then the driver for your computer's sound card could be out-of-date. Many sound card manufacturers frequently update their software drivers. Contact the manufacturer of your sound card or the manufacturer of your computer for an updated driver, or download one from the manufacturer's website. When you have updated the driver, repeat the solutions above.

If no ASIO driver is installed and one is available for your sound card, then download and install the ASIO driver.

Sound is missing from some clips

If sound is missing only from certain clips or only from clips in a certain project, then do the following tasks in order:

1. Check for disabled audio tracks (Premiere Pro CS6).

In the Timeline panel, look at the box at the far left or far upper left of each audio track's header. If no speaker icon appears in this box, then the track is disabled. To enable a disabled audio track, click in the box. A speaker icon appears.

In the illustrated example below, the speaker icon (circled) indicates that the Audio 1 track is enabled. On the right side, the empty box indicates that the Audio 1 track is disabled:

Audio track enabled (left), disabled (right)

2. Check for muted or low track volume.

Use the Audio Mixer or Timeline panel to determine if an audio track is muted or has low volume, and to increase the volume if necessary.

4. Check for clips with incompatible codecs.

If you completed the steps above and you still don't hear sound, the problematic clips could have been encoded with an incompatible codec. Codecs are algorithms for compressing audio and video data. Many different codecs exist. Sometimes, Adobe Premiere Pro can't decode files that were encoded with a poorly designed codec or a codec that is not installed on your computer.

You can download third-party codecs from codec publishers' websites. If the codec used to create the clips isn't available as a QuickTime component, use other software to transcode them with a different audio-encoding format. (Try MPEG Streamclip or QuickTime Player with the QuickTime Pro upgrade.) Then, import the transcoded files into Adobe Premiere Pro.
